摘要：Disclosed are oxygen-scavenging polymer compositions having hightransparency and low haze comprising immiscible blends of at least one polyestercomprising 2,2,4,4-tetramethyl-l ,3-cyclobutanediol, a copolyamide or a transamidized,homogeneous blend of a least two polyamides, and a metal catalyst. The components ofthe immiscible blend which have refractive indices which differ by about 0.006 to about -0.0006. The small difference in the refractive indices enable the incorporation of regrindinto the polymer composition to produce transparent shaped articles. The blends of thepresent invention are useful in producing shaped articles such as, for example, sheeting,films, tubes, bottles, preforms and profiles. These articles may have one or more layers

and can exhibit improved excellent barrier properties and good melt processability whileretaining excellent mechanical properties.
